Title: Improvements in or relating to needle punching machines for making endless webs or strips from fibres or hair
Inventor: FEHRER ERNST
IPC: D04H18/00
Filed: 1968-12-02
Abstract: 1,209,715. Needling apparatus; endless webs. E. FEHRER. 2 Dec., 1968 [11 Jan., 1968], No. 57086/68. Heading D1R. A needle punching machine in which an endless web is guided before and behind a perforated table 1 by rough covered deflecting rollers 7, 6 is characterised in that each deflecting roller 6, 7 is provided with a partcylindrical cover shell 9, 10 having a smooth surface and being pivotally adjustable about the axis of the roller, the cover extending over part of the periphery of the roller preferably less than one-half the periphery. During operation, the shells 9, 10 are in the position shown in dotted lines so that the web contacts the rough surface of the deflecting rollers 6, 7. When the web is completed, the shells 9, 10 are pivoted by means of pistoncylinder units 11, 12 to the position shown in solid lines, so that the web is lifted clear of the roller surface on to the smooth surface of the shell, and the webs can be removed in the direction of the axes of the rollers. When the shells are in the lower inoperative position the leading edge acts as a stripper to prevent the web remaining in contact with the rough surface of the roller. The shells are preferably of hollow crescent-shaped cross-section.

Title: Frequency Control Circuit Arrangements
Inventor: THROWER KEITH REX
IPC: H03M1/00
Filed: 1966-12-31
Abstract: 1,168,438. Automatic frequency control systems. RACAL COMMUNICATIONS Ltd. 24 July, 1967 [31 Dec., 1966], No. 58492/66. Heading H3A. In an A.F.C. system output pulses from a controlled oscillator 10 are counted for a predetermined time and the count compared with a desired number to derive an error signal used to control the frequency of the oscillator. In the arrangement shown in Fig. 1, the oscillator 10 is manually adjusted to a required frequency and the gates 34 and 35 are opened e.g. for one second, to allow pulses derived from the oscillator to pass to the accumulator 38 and to the binary store 40; subsequently the gate 42 is opened to allow a number of pulses corresponding to the number stored in store 40 to pass from the generator 44 and to be subtracted from the number in accumulator 38. Initially the difference is zero, but in subsequent sampling cycles the gate 35 is not opened, so the number in accumulator 38 corresponds to the actual frequency and the number in store 40 to the desired frequency; the difference, positive or negative, is converted into an analogue signal in unit 18 and fed through unit 14 to control the frequency of the oscillator 10. In practice the units 38 and 40 may be down counters, in which case the numbers stored in them are the complements of the numbers of pulses fed in. The number stored in store 40 may be the complement less 64, the extra 64 pulses being supplied to the gate 42 from the generator 44 under the control of a control unit 50; the latter is adjustable manually or electronically to provide more or less than the missing 64 pulses thereby allowing the frequency to be adjusted without altering the number stored in unit 40.

Title: Servo-assisted steering arrangement
IPC: G05D1/02
Filed: 1973-12-19
Abstract: 1435968 Power steering TELDIX GmbH 19 Dec 1973 [23 Dec 1972] 58849/73 Heading B7H In a servo-assisted steering arrangement a plurality of valves controlling pressure medium to the servo piston are controlled by electrically actuatable control means which is made responsive to actuation of the steering wheel. As shown in Fig. 1 two magnetic valves 10, 11 connect chambers 8, 9 of the servo piston 7 to a return pipe 15 in their non-energized state. A further magnetic valve 16 permits the return flow in its non-energized state. The piston 7 is connected to the steering linkage 6. A torque sensing element 20 which is connected into the steering worm sector shaft produces one of two output voltages according to the torque applied by the steering wheel 3. The voltages are passed as pulses through respective AND gates and OR- gates and through an associated amplifier 38 to one of the valves 10 or 11. Thus one of the chambers 8 or 9 is connected for a time to a pressure source 13, 14 so that piston 7 is displaced for turning the wheels 1, 2. A relay 40 is energized if a fault is detected and this cuts off the current to all the valves 10, 11 and 16 to allow for direct steering. An element 45 senses the vehicle deviation from a predetermined line and applies a signal to one of the AND gates 46 which signal is converted to a pulse which is fed to the valves for affecting steering correction. A high frequency pulse generator 49 is provided which picks up a signal indicating an error from terminal 50 and applies alternating energization of the valves 10 and 11 via a generator 49 so that the driver feels a vibration which warns him of an error being present in the system. Chambers 8, 9 of the servo piston are connected to return pipe 15 by throttles (61, 62), Fig. 3 (not shown), so that a damping effect is achieved if the steering is knocked. Valve devices 63, 64 serve to achieve a rapid pressure equalization between return pipe 15 and the chambers 8, 9 for instance in the case where a piston displacement is effected externally. In a modification, Fig. 4, a signal dependent on vehicle speed is fed to a terminal 70 and is converted to a pulse whose width decreases with increasing speed so that a reduction of the influence of a certain steering angle is obtained with increasing speed. Finally a further control of the pulse-pause ratio is provided which is dependent on the speed of ratation of the steering wheel. Similarly the torque applied to the steering wheel is controlled in dependance on vehicle speed. A gate 77 provides an automatic cut out when the servo assistance is not necessary above a predetermined vehicle speed. Provision is also made to compensate for a yawing moment sometimes caused by an anti-lock controller. To achieve this, pressure sensing elements 80, 81 sense the difference in pressure applied to each of the steered wheel brakes and the difference is compared with a signal dependent on operation of the steering wheel applied to terminal 83. A steering adjustment is thus indicated to produce a counter yawing moment.
